Porous PTFE Sheet, release sheet that can allow air circulation
Porous PTFE Sheet has a higher porosity than most Teflon coated fabrics, and this fabric combines fiberglass with lower content of PTFE coating.
This Porous PTFE fabric is used in applications which need airflow pass throw the fabric under pressure (air circulation for drying and curing processes), normal applications including casting sheets for uncured elastomers, vacuum bag bleeder cloth for composite molding in the manufacturing of composite aircraft components.
Unlike PTFE premium series, it is more flexible, much stronger and can be wrapped around curved shapes.
Porous PTFE Sheet
After many years development, Youngsun offering Porous series with balanced PTFE content and porosity.
With high porosity surface, this Porous PTFE Sheet allow air pass the fabric during the production such as vacuum bag bleeder cloth, which allow products to cure and out gas through fabric.
In the meantime, PTFE content will still ensure easy release and high tensile strength. Youngsun will balance these two properties.
Applications of Porous PTFE coated fabrics
Because of their unique properties, these fabrics are excellent for using in a wide range of applications, from the manufacture of polymers to a release medium for composite molding process.
Applications of Porous PTFE Sheet:
★ Aerospace, Communications & Milltary, Composite mold release in vacuum bag, or use as release sheets for fabricating glass-resin structures.
★ Polymer Processing: Manufacture of silicone rubber sheets, Curing rubber and plastic foams and sponge.
★ Insulation and protection.
★ Seperation materials.
★ Drying painted or lacquered products.
★ Release sheet for heat sealing machines
